Patented Apr. 7, 1936 curro SHELF EDGING AND METHOD 0F MAKING THE SAME 1 2 Claims.

This invention'relates to shelf edgings adapted to be secured along the forward edges of shelves inV order to impart a neat and decorative appearance thereto. The invention also consists in the method of producing such edgings.

It has become the vogue to make shelf edgings of a plurality of plies which are frequently of different colors and are so arranged that the plies are successively of greater width from the front to the back of the edging, so that the several plies are visible from the front of the shelf. These several plies are furthermore generally provided with lower edges which are scalloped, picoted or otherwise yornainented or conformed, while the material of the respective plies may be embossed or printed. Through this association of paper plies many novel and pleasing designs are possible,and, when tacked or otherwise secured to the front edge of a shelf, they materially assist in dressing up a pantry or the like.

In the commercial production of edgings of this kind, very effective shelf edgings may be madeA through the use of relatively economical material. The paper stock in many cases is of a relatively cheap texture well adapting it for the purposes for which it is intended, but presenting certain difficulties, more particularly in connection withthe incorporation into the structure of sufficient strength to withstand long usage. g My experience in connection with this situation has convinced me that the best results are obtained when the upper edge of the edging is of a finished character and so bound as to give a smooth nished edge which may be readily ad- ;,ju sted tothe upper surface of the shelf and which will not tend to accumulate dust.

The object of the present invention is primarily to produce in a simple, economical and efficient manner a thoroughly satisfactory upper :edge which not vonly will give a` finished appearance, but will impart added strength to the edging and sufficient rigidity to permit it to properly conform to the shelf and preclude sagging or deformation with respect thereto.

Inone of its preferred practical forms, the edging is made of a plurality of plies of material as heretofore, but either the front or back ply is made so as to extend above the upper edges oflthe other plies. All of the several plies are se- '.cured together, preferably by `an adhesive, in this relation and thereupon the projecting portion of the extended ply is folded over the edges of the other ply or plies and adhesively secured to the opposite face of the edging, so as to form -Ja binding for said upper edges of the other plies (ci. rif-io) and which binding is integralv with either the front or back ply. The resulting construction may be economically manufactured by automatic machinery and produces a smooth, nished edge, which is straight and true. The operation is facilitated by the fact that the projecting portion of the extended ply is -bent over the edges of the other plies which serve as a guide during this operation.` The bending. over of the extended ply further produces a distinct reinforce, which has a pronounced stiffening effect upon the edging and serves to hold 'it inl shape during application to a shelf and after it has been secured in place thereon. l y' vThe several stepsby which the material is manipulated, Varranged in predetermined relation and subsequently-bound and adhesively secured together, constitute a vnovel method forming part of this invention.

Features of the invention, other than those ad.- verted to., will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawing.

The accompanying drawing illustrates different practical embodiments of the invention, but the 25 constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.'

Figure l is a perspective View of a shelf edging embodying the present invention and showing the manner in which the same is made.

Figure-s 2, 3 and 4 are similar views illustrating modified forms of construction also embodying the invention.

Referring first `to Figure l, it will be noted that the edging'in' this showing embodies three plies l, 2 and 3, although any number of plies may be used in this connection. The lower edges of the respective plies are castellated or otherwise shaped in accordance with any predetermined design, while the 'upper edges of the plies 2 and 3 are straight.v The upper'edge of the ply I is shown as straight although it may be scalloped or otherwise shaped without departing from this invention. 45

In the showing of Figure 1, the several plies are superimposed upon one another in such manner that the upper edges of the plies 2 and 3 coincide with one another, while the ply I extends above the upper edges of the plies 2 and 3. All the plies may, when thus positioned, be secured in place by adhesive, indicated at 4 and 5, and this adhesive may be in the form of an uninterrupted band or it may be in the form of areas spaced apart longitudinally of the plies.

After the plies have been secured together in fiat relation, a portion of the ply I will extend beyond the upper edges of the plies 2 and 3, as indicated at 6, and to this extending portion adhesive I is applied and said extension thereupon folded over the upper edges of the plies 2 and 3 and pasted down against the front face of the ply 3. This folding operation may be conveniently carried on with automatic machinery and, during this step, the folding occurs over the edges of the plies 2 and 3, which, being straight, serve as a guide in the formation of a true fold, so as to give a straight and nished upper edge 8.

The extending portion 6 when folded as described constitutes a binding for the upper edge of the edging, completely covers and encloses the upper edges of the plies 2 and 3 and leaves a smooth, finished edge. The adhesive uniting the several parts of the structure at this edge has a pronounced stiffening effect which is enhanced by the extra thickness of the thus bound edge and this greatly facilitates the placing of the edging on a shelf and helps to hold the edging in place thereon against bulging or sagging. Thumb tacks or other devices passed through this bound edge nd adequate support and are not apt to tear loose. Furthermore the whole upper portion of the edging in the region of the binding is rendered substantially solid and homogeneous by the glue bond between all of the parts inthis locality and accordingly the edging has a pronounced backbone where it is most necessary.

In Figure 1 I have shown the back ply I as provided with the extension 6, but it will be apparent that this extension might be formed instead on the front ply 3 and bent over and secured to the back of the back ply. A structure similar to this latterly disclosed form is shown in Figure 2 with slight modification. Here the plies 9 and I0 are superimposed upon one another with the upper edge of the ply I0 spaced from the upper edge of the ply 9. These plies may be secured together independently by an adhesive, but it is not necessary for I may apply an adhesive to the front face of the ply I0 adjacent its upper edge, as shown at II, and to the extending portion of the ply 9, as shown at I2, or to the back face of a third ply I 3, which latter third ply is thereupon attached, so as to overlap both the plies 9 and I 0 and thereafter bodily folded over the upper edge of the ply 9, so as to underlie the latter ply as clearly shown in Figure 2. This structure has the advantage that one pasting operation will secure all of the plies together and after the ply I3A has been folded over beyond the other two plies as shown, it need not be adhesively secured in place, although it may be if desired.

While I have described the upper edges of the plies 2 and 3 in Figure l as coinciding with one another and pasted together, the ply 2 may be made to extend beyond the ply 3 in the same manner as the ply 9 extends beyond the ply I0 in Figure 2, so that when the ply I is folded over, a single gluing operation will serve to hold all of the parts together. Figure 4 shows one of these modied forms of construction, wherein the upper margin of each ply projects beyond the next subjacent or underneath ply with the projecting portion of the uppermost ply extending over the upper marginal portions of all of the other plies and secured, adhesively or otherwise, to the back faces of all of said other plies. In this view, II is the front ply, I9 the back ply and I 8 the intermediate ply.

Figure 3 shows a further modification. Here the plies I4 and I5 are glued together in face abutting relation and thereafter the ply I6 is glued to partially overlap the thus assembled structure after which the projecting portion of the ply I6 is folded over the upper edges of the plies I4 and I5 to underlie these latter plies in face abutting relation therewith. It may be glued in this position or not as desired.

In the several illustrative constructions which I have described any or all of the plies may be shaped, embossed, printed or otherwise ornamented as may be desired and said plies may be of the same or different colors. Furthermore in these several constructions, I have illustrated three plies in each instance, although two or more may be used, the number being immaterial. In all of these structures, however, the same underlying concept is present, namely, the edging embodies a plurality of plies one facial ply of which is provided with a marginal portion projecting beyond the upper edges of the other plies and which marginal portion is extended over the upper edges of said other plies and adhesively secured to the exposed face of the other facial ply. In every instance there is a reinforcement and stiffening of the upper edge of the edging by a binding integral with one of the facial plies and extending over the upper edges of the remaining plies to give a smooth straight edge.

The edging of this invention in any of the forms which I have described may be made either by hand or by automatic machinery and consists in positioning the plies in the manner described. with or without adhesive attachment between them, in combination with the step of folding over the extending marginal portion of one of the facial plies and the securing of this marginal portion to the other facial ply, and, in some cases, to projecting portions of the intermediate plies. This constitutes a novel method of making shelf edgings and forms part of this invention.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claims.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:
